This reverts commit bb10d4ec. Since commit c8ebfad7 ("drm/i915: Ignore OpRegion panel type except on select machines") we ignore the OpRegion panel type except for specific machines (handled via a DMI match), so having SKL explicitly excluded from using the OpRegion panel type is redundant. So let's remove the SKL check. Cc: Jani Nikula <jani.nikula@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by:

The graphics driver is supposed to define the DIDL, which are used for _DOD, not the BIOS. Restore that behaviour. This is basically a revert of commit 3143751f Author: Zhang Rui <rui.zhang@intel.com> Date: Mon Mar 29 15:12:16 2010 +0800 drm/i915: set DIDL using the ACPI video output device _ADR method return. which went out of its way to cater to a specific BIOS, setting up DIDL based on _ADR method. Perhaps that approach worked on that specific machine, but on the machines I checked the _ADR method invents the device identifiers out of thin air if DIDL has not been set. The source for _ADR is also supposed to be the DIDL set by the driver, not the other way around. With this, we'll also limit the number of outputs to what the driver actually has. A side effect of this change is that the DIDL, and by proxy CADL, will be initialized in the order of the connector list. That, in turn, has internal panels in front, ensuring they're included in the DIDL and CADL lists. Hopefully this ensures the BIOS does not block backlight hotkey events, thinking the internal panel is off. v2: do not set ACPI_DEVICE_ID_SCHEME in the device id (Peter Wu) v3: Rebase Cc: Peter Wu <peter@lekensteyn.nl> Cc: Rainer Koenig <Rainer.Koenig@ts.fujitsu.com> Cc: Jan-Marek Glogowski <glogow@fbihome.de> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Marcos Paulo de Souza <marcos.souza.org@gmail.com> Cc: Paolo Stivanin <paolostivanin@fastmail.fm> Tested-by:

Turns out commit a0562819 ("drm/i915: Get panel_type from OpRegion panel details") has regressed quite a few machines. So it looks like we can't use the panel type from OpRegion on all systems, and yet we absolutely must use it on some specific systems. Despite trying, I was unable to find any automagic way to determine if the OpRegion panel type is respectable or not. The only glimmer of hope I had was bit 8 in the SCIC response, but that turned out to not work either (it was always 0 on both types of systems). So, to fix the regressions without breaking the machine we know to need the OpRegion panel type, let's just add a quirk for this. Only specific machines known to require the OpRegion panel type will therefore use it. Everyone else will fall bck to the VBT panel type. The only known machine so far is a "Conrac GmbH IX45GM2". The PCI subsystem ID on this machine is just a generic 8086:2a42, so of no use. Instead we'll go with a DMI match. I suspect we can now also revert commit aeddda06 ("drm/i915: Ignore panel type from OpRegion on SKL") but let's leave that to a separate patch. v2: Do the DMI match in the opregion code directly, as dev_priv->quirks gets populated too late Cc: Rob Kramer <rob@solution-space.com> Cc: Martin van Es <martin@mrvanes.com> Cc: Andrea Arcangeli <aarcange@redhat.com> Cc: Dave Airlie <airlied@linux.ie> Cc: Marco Krüger <krgsch@gmail.com> Cc: Sean Greenslade <sean@seangreenslade.com> Cc: Trudy Tective <bertslany@gmail.com> Cc: Robin Müller <rm1990@gmx.de> Cc: Alexander Kobel <a-kobel@a-kobel.de> Cc: Alexey Shumitsky <alexey.shumitsky@gmail.com> Cc: Emil Andersen Lauridsen <mine809@gmail.com> Cc: oceans112@gmail.com Cc: James Hogan <james@albanarts.com> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: stable@vger.kernel.org References: https://lists.freedesktop.org/archives/intel-gfx/2016-August/105545.html References: https://lists.freedesktop.org/archives/dri-devel/2016-August/116888.html References: https://lists.freedesktop.org/archives/intel-gfx/2016-June/098826.html Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=94825 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97060 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97443 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97363 Fixes: a0562819 ("drm/i915: Get panel_type from OpRegion panel details") Tested-by:

Current intel_opregion_init is called during the driver registration phase and intel_opregion_fini from the unregistration phase. Rename the functions so that this is clear from their names. The phases tell us what we expect the existing hw state to be, e.g. whether interrupts are still enabled etc. It should be noted that the opregion init/fini routines are asymmetric and this is carried across into their new names. Indeed, their new names make it even clearer that perhaps all is not well in the opregion suspend/resume sequence (as well in the module unload). Signed-off-by:

I have noticed some of our interrupt handlers use both dev and dev_priv while they could get away with only dev_priv in the huge majority of cases. Tidying that up had a cascading effect on changing functions prototypes, so relatively big churn factor, but I think it is for the better. For example even where changes cascade out of i915_irq.c, for functions prefixed with intel_, genX_ or <plat>_, it makes more sense to take dev_priv directly anyway. This allows us to eliminate local variables and intermixed usage of dev and dev_priv where only one is good enough. End result is shrinkage of both source and the resulting binary. i915.ko: - .text 000b0899 + .text 000b0619 Or if we look at the Gen8 display irq chain: -00000000000006ad t gen8_irq_handler +0000000000000663 t gen8_irq_handler -0000000000000028 T intel_opregion_asle_intr +0000000000000024 T intel_opregion_asle_intr -000000000000008c t ilk_hpd_irq_handler +000000000000007f t ilk_hpd_irq_handler -0000000000000116 T intel_check_page_flip +0000000000000112 T intel_check_page_flip -000000000000011a T intel_prepare_page_flip +0000000000000119 T intel_prepare_page_flip -0000000000000014 T intel_finish_page_flip_plane +0000000000000013 T intel_finish_page_flip_plane -0000000000000053 t hsw_pipe_crc_irq_handler +000000000000004c t hsw_pipe_crc_irq_handler -000000000000022e t cpt_irq_handler +0000000000000213 t cpt_irq_handler So small shrinkage but it is all fast paths so doesn't harm.

We've had problems on several occasions with using the panel type from the VBT block 40. Usually it seems to be 2, which often doesn't give us the correct timings for the panel. After some more digging I found a way to get a panel type via the OpRegion SWSCI GBDA "Get Panel Details" method. Let's try to use it. The spec has this to say about the output: "Bits [15:8] - Panel Type Bits contain the panel type user setting from CMOS 00h = Not Valid, use default Panel Type & Timings from VBT 01h - 0Fh = Panel Number" Another version of the spec lists the valid range as 1-16, which makes more sense since VBT supports 16 panels. Based on actual results from Rob's G45, 1-16 is what we need to accept. The other bits in the output don't look relevant for the problem at hand. The input is specified as: "Bits [31:4] - Reserved Reserved (must be zero) Bits [3:0] - Panel Number These bits contain the sequential index of Panel, starting at 0 and counting upwards from the first integrated Internal Flat-Panel Display Encoder present, and then from the first external Display Encoder (e.g., S/DVO-B then S/DVO-C) which supports Internal Flat-Panels. 0h - 0Fh = Panel number" For now I've just hardcoded the input panel number as 0. That would seem like a decent choise for LVDS.

SKL and BXT qualifies the HAS_DDI() check, and hence haswell modeset functions are re-used for modeset sequence. But DDI interface doesn't include support for DSI. This patch adds: 1. cases for DSI encoder, in those modeset functions and allows a CRTC modeset 2. Adds call to pre_pll enabled from CRTC modeset function. Nothing needs to be done as such in CRTC for DSI encoder, as PLL, clock and and transcoder programming will be taken care in encoder's pre_enable and pre_pll_enable function. v2: Fixed Jani's review comments. Added INVALID_PORT for non DDI encoder like DSI for platforms having HAS_DDI as true. v3: Rebased on latest drm-nightly branch. Added a WARN_ON for invalid encoder. v4: WARN_ON for invalid encoder is refactored as per Jani's suggestion. Fixed the sequence for pre_pll_enable. v5: Protected DDI code paths in case of DSI encoder calls. Signed-off-by:
